ABSTRACT:
An array of photosensitive sensors each has a storage element to store a pixel value. A repeating fixed pattern noise correction module may be coupled to the photosensitive sensors to correct a repeating fixed noise pattern associated with the stored pixel values. In addition, a non-repeating fixed pattern noise hardware correction module may be coupled to the image sensor to correct a non-repeating fixed pattern noise associated with the pixel values stored in the plurality of elements. In a specific embodiment, one or both of the repeating fixed pattern noise correction module and the non-repeating fixed pattern noise hardware correction module are integrated onto a common substrate with the photosensitive sensors, and can comprise tables to identify specific fixed pattern noise locations.
